Fetching with scrollable cursors

ODBC and embedded SQL provide methods for using scrollable cursors and dynamic scrollable cursors. These methods allow you
to move several rows forward at a time, or to move backward through the result set.

The JDBC and Open Client interfaces do not support scrollable cursors.

Prefetching does not apply to scrollable operations. For example, fetching a row in the reverse direction does not prefetch
several previous rows.
